Mijn, George van der – Antoinette Metayer (1732-88). Oudste zuster van Louis Metayer, 1759 Rijksmuseum: part 3

The picture has something of this: people, portrait, wear, royalty, veil, bonnet, lid, necklace, coat, woman, queen, wig, Renaissance, costume, princess, writer.
Perhaps it’s a painting of a woman holding a dog wearing a black and white dress with a blue sash around her neck.
